PEA-SHELLING DEVICE.

Specification of Letters Patent.

Patented April 23, 1907.

Application filed September 24, 1906. Serial No. 336,857.

invented certain new and useful Improvements in Pea-Shelling Devices, ofwhich the following is a full, clear, and exact description.

The object of this invention is to provide a device or machine of simplecharacter which is efficient for the rapid shelling of peas or like podenclosed vegetables,susceptible in use of having the pods run throughand between a pair of rolls whereby the pods will be broken open and thepeas therein crowded out to roll away and fall from the rear of therolls while the pods are fed and discharged forwardly of the rolls.

Another object of the invention is to construct the pea shelling deviceso as to be used as an attachment for and to have cooperation with partsof a meat reducing or food chopping machine, of a well knowndescription, so that such food reducing machine together with the peashelling appliance to be combined therewith and detached therefrom atthe convenience of the user is rendered more than ordinarily useful in ahousehold.

The present improvements are hereinafter described in connection withthe accompanying drawings and set forth in the claims.

In the drawings,-Figure 1 is a perspective view showing a meat reducingmachine having the pea shellingattachment mounted thereon for use forpea shelling. Fig. 2 is a sectional elevation, on a larger scale,through the pea shelling attachment,parts of the casing shown invertical section being as seen on the plane indicated by line 22,Fig. 1. Fig. 3 is a perspective view of the upper portion of an ordinarymeat reducing machine, having the rotary shaft thereof adapted forreceiving engagement therewith of the pea shelling device, which latterin this view is not shown. Fig. 4 is a perspective View of one of therolls included in the new device. Fig. 5 is a perspective view ofthe'casing. Fig. 6 is a sectional view on the plane of its axis of thesmaller one of the pair of rolls included in the device.

Similar characters of reference indicate corresponding parts in all ofthe views.

In the drawings ,A represents a meat reducing or food chopping machineof a generally well-known description, the same comprising a stand a tobe clamped at the edge of the table or other support and formed with anupwardly opened hopper Z), and a hollow cylindrical extension (Z at thebase of the hopper provided with an end wall having apertures 6 throughwhich the comminuted meat or other substance is expelled by the a crankc.

The shaft at its forward end is constructed with a shoulder 7L, Fig. 3,provided with lugs 'i i, and a screw threaded axial shaft extension j. v

The pea shelling device made as an attachment for, and to havecooperation with, the meat reducing machine above briefly referrred to,will be now described:

D represents a casing comprising opposite side walls or cheeks 10, 10,having opposite axially aligned, comparatively large, journal holes 12,12, at the upper forward portions thereof, and comprising a rear wall13, having an opening 14 through a lower portion thereof and having adownwardly and rearwardly inclined bottom or guide 15 leading to saidrearward opening, and by the extension 15" projected beyond the wall 13.

The casing as shown in Figs. 1, 2, and 5, at a forward portion thereof,and generally below the location of the aforementioned journal holes 12,12, is constructed with a transverse uniting portion or portions 16formed with a guard extension plate or member 17 having an upward andrearward inclination.

The aforementioned casing may be made of a single blank of sheet metal,the intermediate portion thereofforming the back 13, while portions bentat right angles and in suitable separation from each other constitutethe sides or checks, and the members 16, 16, again substantially rightangularly turned to the sides constitute the transverse uniting portion,the same having matched ear lugs 18 fastened together by screws, rivets,or otherwise.

F represents a roll having opposite end hubs m of slight axial extent,the same being sprung or otherwise engaged in place within the journalholes 12, 12, of the casing sides, said roll having also a hole 20axially therethrough whereby it is fitted onto the extenl sion of therotary shaft B, and by the sockscrew 9 which is carried on a shaft Bhaving ets 22 within the face of one of the hubs, which is locatedtowards the apertured end wall f of the meat reducing machine,engagement is made between the roll F and shaft B whereby the latterwill be positively turned in unison with the former. The thumb nut tclamps the device in its supporting engagement on the shaft B.

G represents a second roll, advantageously of smaller diameter than thatof the roll F 1 and this smaller roll is j ournaled within the casing Dby having journals or axial studs 25 fitting in journal holes 26 in theopposite side walls 10, 10, of the casing. The smaller roll ispositioned peripherally adjacent to, but not in contact with, the rollF, and it is located with its axis below and to the rear of the axis ofthe larger roll. The body of the roll G may advantageously be made ofsemielastic rubber.

The comparatively short rolls F and G have on their ends intermeshingspur gear wheels n and 0 so that by turning of the shaft B both of therolls are rotated for the pod feeding and pea expelling action.

As an occasion may render desirable, the improved device or pea shellingattachment is mounted in place in its combination with the shaft of themachine A, and while the shaft is being continuously turned, the peas inpods may be rapidly fed in succession between the rolls F and G with theeffect of compressing the pods, breaking them open; and while the podsin flattened condition are fed and discharged forwardly and downwardly,the peas, which are crowded out from the opened pods by the rolls, willroll rearwardly to fall from the lower and smaller roll 9 onto thedownwardly and rearwardly inclined bottom or guide 15 of the casing, tobe conveyed through the opening 14 into a shallow pan or otherreceptacle in place therefor.

The guard 17, the edge of which is in con tact against or proximity tothe periphery of the roll F prevents any of the flattened pods whichmight adhere to the roll from being carried around with the roll to asecond time pass between the pair of rolls.

It will be seen that, during use of the device, rotation of the casingwill be prevented by the engagement of the lower end of the rear wall 13with the bottom of the receptacle into which the peas are being shelled,the wall being extended downward below the rolls for this purpose.
